The Oil Cooling Unit is a cooling unit using a refrigeration cycle shown in Figure above, which is different from air conditioners in the object to cool. The Oil Cooling Unit is subject to cooling of oil, while air conditioners are subject to cooling of air. Consequently, knowledge required for basic services is the same as that for air conditioners but different in some points particularly from the air conditioners. The following section describes these different points.1. Functions of Electronic Expansion ValveThe electronic expansion valve is used for capacity control at a frequency below the minimum compressor operating frequency, thus having characteristics shown below.q While in low capacity operation, the electronic expansion valve uses the low-pressure region, which no air conditioners use.w The fully closed point of electronic expansion valve (fully closed pulse of EV valve) should be set with the PC board by each unit. (In order to replace the EV valve or PC board, pay attention to this point.)2. Oil PumpSince the Oil Cooling Unit is subject to cooling of oil, an oil pump is incorporated in place of a fan on the indoor side. The following section describes the features of the oil pump.q When the external resistance reaches 0.5 MPa or more, the relief valve will be activated.w Since the external resistance block (field piping) is an item to be designed by the user, attention should be paid.3. Characteristics of Electrical SystemBasically, the electrical system is the same as that of air conditioners but has the following characteristics.q The Oil Cooling Units has nothing equivalent to the operation switch. Be noted that the Oil Cooling Unit starts running as soon as the power supply turns ON. Normally, the Oil Cooling Unit exchanges signals with a machine tool and runs under ON-OFF control on the machine tool side.w The Oil Cooling Unit has an enhanced readout function of internal product data.
